CHECKOUT SYSTEM, CHECKOUT DEVICE, CHECKOUT METHOD, AND PROGRAM

摘要

The present invention addresses the problem of preventing products from being carried outside a store without complete a checkout process in a checkout system in which a product, a shopping basket in which the product is accommodated, or a shopping cart in which the product is accommodated is disposed in a checkout device when performing a checkout process. In order to solve the problem, a product registration device (10) registers the product. The checkout device (20) performs the checkout process for the product registered by the product registration device (10). An output unit (320) outputs information indicating that a target object (30) (in the example shown in the drawing, a shopping cart (32) in which a product is accommodated) has moved from the checkout device (20) on the basis of the presence or absence of movement of the target object (30) from the checkout device (20), and the state of the checkout process.
